REENFORCED GL'Ass SUBSTITUTE.. f

Application filed October 4, 1926. Serial No. 139,524.

The invention relates to glass substitutes and has for itsobject the fabric base with transverse and longitudinally disposed strands of heavier thread or of wire, which will thory oughly brace the fabric, hold the same together after deterioration has set in incident to the deterioration of the threads of the fabric, and at the same time bulging of a sheet of material when in position will be prevented.

A further object is to provide a glass slibstitute having a fabric base and longitudinally and transversely disposed strands of heavier material thereby forming recesses in which the paraffin or other material used Will be relatively heavy, thereby additionally bracing, the fabric, and in combination with the large reenforcing strands providing a glass substitute which will stand upA under all conditions of weather, and one which will transmit the maximum quantity of ultra-violet rays, which is conducive to the health of hu-v man beings as well as poultry and plant life. The squares formed by the reenforced strands absorb more of the processing mixture, and in the cooling process tends to give a more evenly finished produc-t and insures longer and more satisfactory wearing qualities and y at the same time the advantages of a heavier material are obtained without loss of its translucent qualities which would be the case with a heavy fabric, and at the same time the lighter fabric reenforced can be easily handled` which is not the case with lighter fabric.

With the above and other objects in View the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed,

it being understood that changes in the prey, cise embodiment ofthe invention may be made Within the scope of what is claimed without departing from the spirit of the invention.

In the drawings:

Figure 1 is a plan view of a sheet of material showing the reenforcing strands therein.

Figure 2 is a plan view of a portion of the fabric showing the reenforcing strands therein.

Figure 3 is a perspective detail sectional view through a portion of the sheet of material.

Referring to the drawing, the numeral l designates the sheet of fabric, which fabric is run throughs. composition, for instance paraffin for rendering the same translucent for use in connection with poultry houses, or

wherever a translucent housing is desired,

for instance'porches of homes or hospitals, Where this type of material is coming into extensive use. It has been found that Where the fabric 1 is used with a coating, the sheets of material, especially Where large will often bulge, and the sheets cannot be stretched to position Without damage to the sheet. It has alsobeeii. found that where a very heavy fabric is used, the translucency thereof is materially reduced, consequently ultra violet rays are cut off. To obviate the above difliculties the fabric 1, preferably during the course of manufacture --is provided with transversely and .longitudinally disposed threads 2 and 3, woven therein or stitched therein as desired, and which threads are heavier than the thread forming the fabric 1. Threads 2 and 3 preferably cross each other at right angles, thereby forming square areas a, which receive a thicker layer of material as clearly shown in Figure 3, as it has been found that this area will absorb more of the processing mixture when divided into areas and during the cooling process tends to give a more evenly finished product ony account of the relative thickness thereof,

consequent-ly insures longer and more satisfactory wearing qualities. The large strands 2 and 3 may be formed from fibre or from wire, and applicants do not limit themselves to the particular material, or to the crossing.

of the strands 2 and 3 at right angles, as it is obvious the strands may cross at other angles. 1t will be noted by providing the reenforcing strands 2 and 3, thicker zones of coatincr material are insured and a sheet of niaterialmay be stretched to its position Without damaging the same, and stretching of the material is obviated. It will also be seen byproviding the large reenforcing strands 2-and-3 a relatively light vveight fabric 1 may be used which Will give the maximum transparency, but at the same time the reenforcing strands 2 and 3 furnish the additional strength for forming a strong material and all of the advantages of the undesirable heavy fabric Without the objectionable features thereof, that is lack of transparency and slow absorption, as well as labor incident to handling heavy fabric during the course of manufacture.

From the above it will be seen that a reenforced glass substitute is provided having a fabric base which is reenforced by larger strands crossin each other angularly, and a better and thicker coating may be applied to the fabr'ic incident to the rectangular shaped areas formed by the'fcross strands.

The invention having been'set forth what is claimed as new and useful is 1. A glass substitute for transmitting ultra violet rays comprising a Woven fabric base having reenforcing textile strands extending through said fabric base in spaced relation andy of heavier material than the other strands of the fabric base and a translucent material carried by said fabric base andv reen forcing' textile strands.

2. A glass substitute for transmitting ultra violet rays comprising a Woven fabric base having reenforcing textile strands extending through said fabric base, said reenforcing textile strands being in spaced crossed relation thereby forming zones between the reenforcing textile strands and a translucent material carried by said fabric base and reenforcing textile strands. i

In testimony whereof We"l1ereunto aflix our signatures.
